Loran for Required Navigation Performance 0 . 3 : The Current Work of Loran Integrity Performance Panel ( LORIPP )

Loran, is an attractive candidate to provide backup services for GPS because of its complementary area navigation (RNAV), stratum 1 timing, and data channel capabilities. However, for Loran to be accepted as a backup navigation system for aviation, it must meet the integrity, availability, continuity, and accuracy standards for Required Navigation Performance 0.3 (RNP 0.3). The Loran Integrity Performance Panel (LORIPP) is a core team of experts assessing Loran’s potential to meet the RNP 0.3 performance. It applies engineering and safety analysis principles to build in safety as an integral part of the system design. The LORIPP is following safety analysis methods similar to those used by the WAAS Integrity Performance Panel (WIPP) to conduct a rigorous Hazardously Misleading Information (HMI) analysis on Loran.
